Title: Improvements in and relating to powdered coatings
Inventor: LAWSON KENNETH THOMAS
IPC: B05B7/14
Filed: 1964-09-28
Abstract: In a method and apparatus of coating a continuously moving metal strip e.g. steel with a powder such as A1 powder (120 mesh to dust) the powder is fed from a hopper to a metering device such as a rotating roll with a number of spaced circumferential grooves which receive the powder and discharge the powder as a series of streams on to a vibrating screen where the powder is electostatically charged prior to dispersal on the electrically earthed moving strip. According to Fig. 1 (not shown) the powder is stored in a hopper 3 comprising a steel retaining blade 16 bearing on metering roll 4 and a compacting blade 17 which forces the powder flowing from the hopper into the grooves 12 on the metering roll as the roll rotates.  The powder in the hopper is agitated by a vibrator 19 and a scraper 21 removes excess powder adhering to the roll 4.  The speed of rotation of roll 4 determines the volume of powder and this is discharged from the grooves by fingers 23.  The powder streams are diffused on vibrating screen 5 which is electrically charged to 30kV and then are attracted to the moving earthed strip S.ALSO:In a method and apparatus of coating a continuously moving metal strip e.g. steel with a powder such as A1 powder (120 mesh to dust) the powder is fed from a hopper to a metering device such as a rotating roll with a number of spaced circumferential grooves which receive the powder and discharge the powder as a series of streams on to a vibrating screen where the powder is electrostatically charged prior to dispersal on the electrically earthed moving strip.

Abstract: A coherent non-woven sheet which may be coated with polymeric or non-polymeric material (see below) comprises one or more continuous plexifilaments (a plexifilament being, as disclosed in Specification 891,943, a yarn-like strand which is defined as a continuous extruded or spun shaped filamentary structure of a crystalline synthetic polymer comprising a three dimensional integral plexus and characterized in that the plexus is composed of a multitude of molecularly oriented film-like and/or ribbon-like structural units, referred to as "film fibrils", which unite and separate at random intervals along and across the plexus) in which the film fibrils have an average thickness less than 4 microns, the plexifilament or plexifilaments being arranged in an overlapping and intersecting relationship and the sheet being consolidated to such a degree that it has an overall tensile strength greater than 0,3 lb./in./oz./yd.2. The plexifilaments may be in two or more layers, each layer consisting essentially of a plurality of substantially parallel strands of plexifilamentary material.  The plexifilaments may be fused together either by heat or mechanical means and the sheet may be embossed so as to give raised and depressed portions, the plexifilaments being self-bonded in the depressed portions to a greater density than in the raised portions.  The synthetic polymer of some or all the plexifilaments is preferably polyethylene or a blend of linear polyethylene and minor amounts of branched polyethylene or a blend of polyethylene and polyisobutylene.  In forming such non-woven sheets a batt is formed by arranging in an overlapping and intersecting relationship one or more continuous plexifilaments and the batt is then consolidated into a sheet.  The spinning of the plexifilament or plexifilaments and the formation of the batt may be carried out in a continuous operation and the consolidating may be done by calendering with or without heat fusing of some of the plexifilaments.  The batt may be formed in layers by laying first in one direction and then at approximately 90 degrees thereto and such a batt may be subjected to calendering to produce a single sheet.  The sheet material may be coated with polymeric or non-polymeric materials.  The latter include waxes, dyes, pigments, &c. Polymeric compositions include polyethylene, polypropylene, polyisobutylene, natural rubber, neoprene, chlorosulphonated polyethylene, polyvinyl chloride and various vinyl halide and vinyl ester polymers and interpolymers.  These polymeric compositions may be applied by either melt, solvent or dispersion techniques, calendering, dipping, direct extrusion and "kiss-roll" methods.

Title: Capacitive networks
IPC: H01G4/38
Filed: 1969-08-19
Abstract: 1,220,567. Capacitors. SIEMENS A.G. 19 Aug., 1969 [20 Aug., 1968], No. 41222/69. Heading H1M. A capacitive network is derived from a parent capacitor consisting of two electrodes or two sets of electrodes, adjacent electrodes being separated by dielectric material and electrodes of opposite polarity being staggered so that they extend to opposite end faces of the capacitor, the network being obtained by making cuts each extending from an end face over at least the whole width of the overlapping zone, but not extending to the other end face. As shown cuts 3 and 5 are made from one end face, cut 4 from the other to give four series-connected capacitors between terminals a and b (see also Fig. 2, not shown) suitable for use as a voltage divider. By making all the cuts from one face a parallel arrangement of capacitors is obtained (Figs. 3, 4, not shown). Resistors, inductors and other components may be connected between the subsidiary capacitors to give more complex networks. In other embodiments (Figs. 5 to 8, not shown) T and # capacitor networks are obtained, or arrangements for use as suppressors (Figs. 9 to 12, not shown). The cuts may be filled with insulating material, e.g. by potting the component. The individual capacitor units formed by making the cuts may themselves comprise an arrangement of seriesconnected capacitors by removing strips of electrode material at right angles to the cuts (Fig. 13, not shown). Alternatively where the electrodes are formed by metallizing the dielectric, unmetallized strips may be left.
